Congenital pseudarthrosis of the forearm: treatment of six cases with vascularized fibular graft and a review of the literature.

Six cases of pseudarthrosis of the forearm are reported. One involved only the radius, one the ulna alone, and four both forearm bones. There was associated neurofibromatosis in five cases. All the cases were treated by wide resection and free vascularized fibular graft. In two cases, a single-bone forearm was created. In all cases, good results were achieved, with moderate forearm shortening. The literature suggests electrical stimulation, corticoperiosteal graft, osteotomy of the involved bone, and free vascularized bone grafting as treatment alternatives. Vascularized free bone grafting appears to be more successful than other treatments. The use of microsurgical sutures permits this treatment in young patients.

Treatment of congenital pseudarthrosis of the tibia by microsurgical fibula transfer.

Conventional methods for the treatment of congenital pseudarthrosis of the tibia (CPT) often lead to unsatisfactory results and so microsurgical fibula transfer (MFT) has appeared as an option to treat this challenging problem. In this series of 27 patients with CPT, we obtained satisfactory results in 23 as assessed by the timing of bone union and bone hypertrophy of the fibular transplant. The overall functional results were also good; in 18 patients, the residual shortening was less than 2 cm (with no limb shortening in 4) and in 7, shortening ranged between 2 and 4 cm. All 25 patients resumed normal walking without the help of braces after an average of 12 months. This report suggests that microvascular fibula transfers provide superior results in the treatment of CPT, especially when considering that many of such cases represented previous surgical failures.

Pseudarthrosis and delayed union after anterior cervical fusion.

Anterior cervical spine fusion was carried out on 443 cases between 1965 and 1988 with pseudarthrosis or delayed union in 15 (3.4%). The causes of these complications were malalignment and faulty postoperative care. Symptoms resulted from abnormal mobility, cord compression due to posterior slip or rotation of the upper vertebral body, kyphotic deformity or a problem at the adjacent level. Four out 5 cases with symptoms recovered successfully after a second operation.

The differential diagnosis of congenital pseudarthrosis of the tibia.

The key to the solution of this problem lies in the differential diagnosis. There are at least four dysplastic lesions of the congentially bowed tibia (with or without cysts) which have quite different behaviour patterns. There are also six different types of true congenital pseudarthrosis which exhibit similar differences in behaviour and response to treatment.

Spinal pseudarthrosis with paraplegia in ankylosing spondylitis. A case report.

Destructive lesions of vertebral bodies in ankylosing spondylitis (AS) have for a long time been regarded as inflammatory changes, sometimes of tuberculous etiology. However, observations during recent years have established that these destructions in fact are non-unions after fractures. A case of spinal pseudarthrosis with paraplegia in a patient with advanced AS is presented. After combined anterior and posterior decompression as well as fusion using plate fixation, the neurological symptoms regressed completely and early mobilization of the patient was possible.

[Causes and treatment of delayed callusformation and pseudarthrosis following fractures of the shaft of the humerus (author's transl)].

In the OHH, during the years 1969 to 1974, 28 patients were operatively treated because of delayed callusformation or pseud-arthrosis, following a fracture of the shaft of the humerus. It was possible to inquire about and to re-examine 20 patients. The operative treatment had, when possible been achieved by osteosynthesis through plates (25 cases). Each of the so treated cases lead to healing of the bone, additional nerve lesion did not in one case occur because of the operation. Objectively seen, there existed in 7 patients a slight, final restriction of movements, for the abduction and outside rotation in the shoulder joint. 6 patients complained of being sensitive to weather changes. The different treatment method of the fracture of the humerus and pseudarthrosis was discussed.

[The tendon interposition plastic with partly necrosised scaphoid pseudarthrosis (author's transl)].

We have seen in 4 cases of 46 operated scaphoid pseudarthrosis aseptic bone necrosis of a fragment. According to the tendon interposition plastic of Froimson for the substitute arthrose of the saddlepoint of the thumb. We exstirpated the bionecrotic fragment of the scaphoid, splitted the tendon of the flexor carpi radialis muscle, removed a part of the tendon from the belly of the muscle, rolled it in and fixed it in the excavated cavity of the bone. After an observation time of 6 months to 1.5 years all 4 patients have not developed complications.

Pseudarthrosis resulting in complete paraplegia fifteen years after spinal fusion.

Paraplegia immediately following spinal fusion is a known problem. This case demonstrates the importance of long-term follow-up of fusion patients. Prompt attention must be given to any change in neurological status. A careful check must be made for pseudarthrosis and for secondary compression of the spinal cord as possible causes of neurological compromise.

Treatment of infected tibial pseudarthrosis by external fixation with the Wagner device.

We analyzed our experience with infected tibial pseudoarthrosis which resulted in a therapeutic plan for a radical operation or a step-by-step method, depending on the type of pseudarthrosis (PS), the severity of the infection, and the skin damage. We think that external fixation with the Wagner device is the procedure of choice. Owing to its simplicity and good stability, it is possible to treat the PS and the infection and to obtain good final results.

Bilateral pseudarthrosis of the femur after stress fracture.

Stress fractures of the diaphysis of the femur are very rare, particularly bilateral ones. We describe here a woman patient with bilateral pseudoarthrosis of the femoral diaphysis which was the result of a stress fracture. The case is a rarity because the in question is of a dwarfism stature with great deformation of the lower extremities due to rickets. The patient has been closely examined for over 30 years. Our own explanation for the beginnings of stress fracture as well as for the pseudarthrosis development are given.

Glycosaminoglycans in congenital pseudarthrosis.

Light and electron microscopic studies on cells and matrices of congenital pseudarthrosis of the femur of a 5.5-year-old male revealed three areas with different morphological features; a fibrous area, a cartilaginous area and an osseous area. Glycosaminoglycans were isolated from each of the three areas and characterized by the degradation with chondroitinases. Although chondroitin sulfate was the major component in all regions, a significant amount of dermatan sulfate occurred in the fibrous area. A small amount of hyaluronic acid was found in both fibrous and osseous areas. These suggest that the peculiar composition of glycosaminoglycans in the affected part may account for some clinical aspects of the disease which resists treatment.

Long-term pulsed electromagnetic field (PEMF) results in congenital pseudarthrosis.

Ninety-one patients with congenital pseudarthrosis of the tibia have been treated with pulsed electromagnetic fields (PEMFs) since 1973 and all except 4 followed to puberty. Lesions were stratified by roentgenographic appearance. Type I and type II had gaps less than 5 mm in width. Type III were atrophic, spindled, and had gaps in excess of 5 mm. Overall success in type I and II lesions was 43 of 60 (72%). Of those 28 patients seen before operative repair had been attempted, 7 of 8 type I lesions healed (88%), whereas 16 of 20 type II lesions healed (80%) on PEMFs and immobilization alone. Only 19% (6 of 31) type III lesions united, only one of which did not require surgery. Sixteen of 91 limbs (18%) were ultimately amputed, most before treatment principles were fully defined in 1980. Fourteen of these 16 patients (88%) had type III lesions. Refracture occurred in 22 patients, most as the result of significant trauma, in the absence of external brace support. Twelve of the 19 refractures, retreated with PEMFs and casts, healed on this regime. Episodic use of PEMFs proved effective in controlling stress fractures in several patients until they reached puberty. PEMFs, which are associated with no known risk, appear to be an effective, conservative adjunct in the management of this therapeutically challenging, congenital lesions.

[Delayed union and pseudarthrosis of the carpal navicular: diagnosis and treatment (author's transl)].

Knowledge of the pathophysiological ways and the changes by roentgenogram after fracture of the carpal navicular makes it possible to get an exact diagnosis of the stage of the fracture. The diagnosis will show the way to the correct treatment. The results in 31 cases with an average follow-up of 15 years are presented. In our series it is pointed out that the real pseudarthrosis can only be healed by operative treatment. All 13 operatively treated pseudarthroses had healed by way of ossification and 11 patients without treatment still suffer from pseudarthroses. 10 of these 11 cases show later arthritic or degenerative changes. In cases of traumatic cysts primary operative treatment is preferred. Severe pre-existing arthritis with sclerosis requires a palliative operation in all cases.

[Coracoid pseudarthrosis caused by anterior shoulder dislocation with concomitant coracoid fracture].

Fractures of the coracoid process are rare and represent only 2-5% of all fractures of the scapula. The most frequent cause of a coracoid fracture is direct trauma, but indirect trauma may also lead to a fracture of this kind. Avulsion injuries as part of an acromioclavicular dislocation are the most frequent forms of trauma. For the rare cases of an anterior shoulder dislocation with concomitant coracoid fracture, two different mechanism are discussed. One cause of the coracoid fracture could be direct impact of the dislocated head of the humerus on the coracoid process, another may be the occurrence of a sudden strong pull of the muscles inserting at the coracoid process during shoulder dislocation.In the majority of cases, conservative treatment with six weeks of immobilization is appropriate. If a pseudarthrosis occurs and there is persistent pain, we recommend the operative fixation of the distal coracoid fragment by insertion of cancellous bone graft taken from the iliac crest and stabilization with a cannulated AO titanium small fragment screw and PDS cord.

[Distinctive features of the os naviculare pseudarthrosis vs the os naviculare accessorius].

We report on two cases in which the differential diagnosis between an os tibiale externum (os naviculare accessorius) and a post-traumatic pseudarthrosis of the os naviculare was subject to discussion.Both patients had suffered an acute trauma in the region of the middle foot and showed identical clinical symptoms. Conventional X-ray did not allow a definite classification of the diagnosis either.However, this was possible in both cases by virtue of typical signs evidenced by computed tomography and magnetic resonance imaging.
